The Abant trout is a salmonid fish native to Lake Abant in northern Anatolia. It was initially described as a subspecies of the brown trout Salmo trutta abanticus Tortonese, 1954, but later even considered a full species Salmo abanticus. On the basis of crossing experiments and mtDNA sequences, Kalayci et al. (2018) however proposed that it should be considered a local strain within Salmo trutta, with no distinct species status. The native lake has no significant tributaries but is fed by water from springs.
